More importantly, some non-coding RNAs were considered as the known prognosis biomarkers in thyroid cancer, such as let-7a, LINC-PINT, H19, MALAT1 and HOXA-AS2 (Chu et al., 2017; Liu et al., 2017; Dai et al., 2019; Jiang et al., 2019; He et al., 2021). The gene discussed is HOXA-AS2; the disease is thyroid cancer.
